A blower fan 14 is arranged below the inside of the frame body 2, and a heat exchanger 16 is arranged above the blower fan 14. At least one of the outlet 6 and the lower outlet 8 blows out into the room. Therefore, the heat exchanger 16 is located on the downstream side of the blower fan 14 when viewed from the flow of air passing through the inside of the casing 2 .

In addition, a plurality of (for example, 3 blades, i.e., upper blade, middle blade, and lower blade) vertical airflow direction adjustment blades 18 extending in the lateral direction are arranged on the upper blowing port 6 for adjusting the air blown to its front side up and down. The wind direction control of upper part outlet 6 is arranged with a plurality of (for example 9) left and right wind direction regulating blades 20 extending in the longitudinal direction at the rear side of the upper part blower port 6, and is used to control the left and right wind direction of the blown air. Each up and down wind direction regulating blade 18 (upper blade, middle blade, lower blade) is respectively connected with a driving motor (not shown), and by driving the driving motor, each up and down wind direction regulating blade 18 can be controlled independently and freely swinging up and down. On the other hand, the left and right wind direction adjusting blades 20 are divided into three blocks each of which is three on the left side, three on the center, and three on the right side. The three left and right wind direction adjustment blades 20 constituting each block are connected to each other with a connecting frame, and when one of the blades is connected to the drive mechanism, the angle of the left and right wind direction adjustment blades 20 can be changed independently for each block.

A plurality of (for example, 12) left and right wind direction regulating blades 26 are used to control the left and right wind direction of the blown air. When the air conditioner was stopped, the lower outlet 8 could be closed by the up and down wind direction adjustment blades 24, and the up and down wind direction adjustment blades 24 acted as the cover of the lower air outlet 8, so that the left and right wind direction adjustment blades 26 could not be seen from the outside. In addition, the up and down wind direction adjustment blades 24 are connected to a driving motor (not shown), and the driving motor can be freely controlled to swing up and down. On the other hand, a plurality of blades among the left and right wind direction adjusting blades 26 are connected to each other by a connecting frame, and when one of them is connected to a drive motor, the angles of the plurality of blades can be changed integrally.

In addition, as shown in FIG. 3 , the lower front part of the indoor unit frame 2 is a vertical plane, and the upper front part is formed in an arc shape in a manner that gradually recedes upward. When the air conditioner is in operation, even if the upper outlet 6 is opened In this state, the front edge of the upper panel 22 and the upper vertical airflow direction adjustment vane 18 is dimensioned so that the surface extending directly above the lower front does not protrude to the front, so it does not hinder the movement in front of the indoor unit. people and objects.

In addition, the size of the lower up and down airflow direction adjusting blades 24 is also set so as not to protrude forward from the front of the indoor unit frame 2, which will be described in detail later.

In addition, in Fig. 1 and Fig. 2, although the floor-standing air conditioner in which the upper air outlet 6 is provided at one place on the front upper part of the frame body 2 is shown in the figure, it may also be arranged on the left and right sides of the front upper part of the frame body 2. There are two, and one upper outlet 6 is arranged on the top surface, and the position of the upper outlet 6 is not particularly limited.

<The lower up and down air direction adjustment blade and its driving mechanism>

Fig. 4 and Fig. 5 represent bottom up and down wind direction adjustment vane 24 and its drive mechanism, bottom up and down wind direction adjustment blade 24, have upper connecting shaft mounting part 52 and lower connecting shaft mounting part 54 at its left and right ends respectively, top connecting shaft 56 Both ends are mounted on the left and right upper connecting shaft mounting parts 52 , and both ends of the lower connecting shaft 58 are mounted on the left and right lower connecting shaft mounting parts 54 .

In addition, an upper guide groove 60 and a lower guide groove 62 are formed on the left and right side walls 2a of the indoor unit frame body 2 where the height of the lower up and down airflow direction adjustment blades 24 is adjusted, and the two ends of the upper connecting shaft 56 are inserted into the left and right sides respectively. In the upper guide groove 60 , both ends of the lower connecting shaft 58 are inserted into the left and right lower guide grooves 62 so as to loosely fit. The upper guide groove 60 is formed in a straight line and extends gradually upward from the front of the side wall 2a to the rear. On the other hand, the lower guide groove 62 is formed in an arc shape so as to rise sharply from the front of the side wall 2a to the rear. The way up is extended.

In addition, a drive shaft 64 is rotatably attached to the rear of the lower up and down wind direction adjustment blades 24, and the drive shaft 64 is connected to a drive motor (not shown). One end of the arm 66 is fixed to one end of the drive shaft 64, and the other end of the arm 66 is formed with a long hole 66a, and the upper connecting shaft 56 is loosely inserted into the long hole 66a. In addition, a concave portion 2b is formed on the inner surface of one (left side wall) of the left and right side walls 2a for accommodating the swingable arm 66. Since the arm 66 can swing in the concave portion 2b, the concave portion 2b is fan-shaped.

When the air conditioner stopped, the bottom up and down wind direction adjustment blades 24 of the above structure could close the lower outlet 8 as shown in Figure 4. In this state, dust and foreign matter would not flow into the frame through the lower outlet 8. When the air conditioner starts to operate, if the drive shaft 64 is driven by the drive motor, the arm 66 swings backward, and the two ends of the connecting shaft 56 are guided to the guide groove 60, and gradually rise toward the rear along the upper guide groove 60. . At this time, both ends of the lower connecting shaft 58 are guided to the lower guiding groove 62, and rise sharply rearward along the lower guiding groove 62. When the two ends of the upper connecting shaft 56 reach the rear end (upper end) of the upper guiding groove 60, The two ends of the lower connecting shaft 58 reach the rear end (upper end) of the lower guide groove 62. As shown in FIG. Keep. Therefore, it is possible to perform air-conditioning control aimed at the person's feet.

In addition, since the drive motor is set to rotate the drive shaft 64 at any angle, the upper connection shaft 56 can be driven by the drive shaft 64 and stopped at any position of the upper guide groove 60, the position of the lower connection shaft 58 depends on At the position of the upper connecting shaft 56. Therefore, as shown in FIG. 6, the lower up and down wind direction adjustment vane 24 can be set to any inclination angle between the state of FIG. 4 and the state of FIG. Wind direction control, excellent versatility.

As mentioned above, the driving mechanism of the bottom up and down wind direction adjustment blades 24 is composed of the upper connecting shaft 56, the lower connecting shaft 58, the upper guiding groove 60, the lower guiding groove 62, the driving shaft 64 and the arm 66. Both ends and the two ends of the lower connecting shaft 58 are loosely inserted into the upper and lower guide grooves 60, 62 respectively, so there is no need for too many components when the lower up and down wind direction adjustment blades 24 move.

In addition, FIG. 6 shows the trajectory of the lower up and down wind direction adjustment blades 24 when the lower outlet 8 is from closed to fully open. Since the upper end of the lower guide groove 62 is arranged more rearward than the lower end, the lower outlet 8 is adjusted from closed to fully open. When the front edge (lower edge) of the lower up and down wind direction regulating vane 24 rises in a straight line in the manner of gradually receding upward, not only the front edge of the lower part up and down wind direction regulating blade 24, but also all the lower up and down wind direction regulating blades 24 are lower than the lower blowing outlet. 8 The front does not protrude forward when closed (when the air regulator is stopped). That is, since the lower part air outlet 8 is approximately at the same height as a part of the child's body (head, shoulders, etc.), when the lower up and down wind direction adjustment blades 24 are moved to the inside of the frame, no matter in any state, the lower part up and down wind direction adjustment blades Any part of 24 can not protrude to the front of indoor unit frame body 2, carries out size setting in this way, thereby becomes the safety design that people can not contact with a part of bottom up and down wind direction adjustment blade 24.

7 and 8 show the same state as in FIG. 4 in which the lower up and down wind direction adjusting vane 24 closes the lower blowing outlet 8, and the lower left and right wind direction adjusting vane 26 is driven to a position parallel to the front of the indoor unit frame 2 and closes the lower blowing outlet. exit 8. On the other hand, FIG. 9 and FIG. 10 show the same state as in FIG. 5 in which the lower up and down air direction adjustment blades 24 open the lower air outlet 8, and the lower left and right air direction adjustment blades 26 are driven to a position perpendicular to the front of the indoor unit frame 2. And open the lower blowing outlet 8.

In addition, by setting the lower left and right wind direction adjustment vanes 26 at the lower blowing outlet 8, the air blown out from the lower blowing outlet 8 can be controlled in the left and right direction, so that precise air conditioning control can be performed. By combining with the upper blowing outlet 6, the More precise air conditioning control is possible.

Then, when only the air is blown out from the upper outlet 6, the lower outlet 8 is closed by the lower vertical wind direction adjustment blade 24 and the lower left and right air direction adjustment blade 26, so the sealing performance of the lower outlet 8 is further improved. In particular, during cooling operation, leakage of cold air from the lower outlet 8 can be greatly reduced, thereby preventing condensation near the lower outlet 8 .
